9V Digital Continuity Circuit Tester Buzzer Wire PCB Cable Detector with LED Indicator Light for Electronics Testing(C)

Features:The product has a buzzer sound prompt, and the volume is about 100 decibels. It also has an indicator light prompt.1. How to use: After plugging in the test , touch the two ends of the measured wire. If an audible and visual alarm is issued, it means that the wire is conducting, otherwise it is not conducting.2. This product has a built-in 9V , and the cover can be opened to replace the . As shown in the principle diagram, if the red and black ends are not measured, the is not conducting and there is no current consumption.3. After the measurement circuit is turned on, the loop current is about 20ma. This product is not suitable for measuring tiny electronic components, electronic circuit , .Specifications:Part name: 9V buzzer testerMaterial: ABSColor: WhiteSize: 93*55*30mm--You can test whether the cable is normal, whether the wire is normal, whether the PCB board cable is normal, or whether the product is normal.--Precautions: Do not use when the product is powered on or plugged in to a power source!Package Contents:A: 1*continuity tester (without wire)B: 1*continuity tester + 1*red and black clip wireC: 1*continuity tester + 1*multimeter pen wireD: 1*continuity tester + 1*multimeter pen wire + 1*red and black clip wire
